There is a great project on CodePlex called Flickr.Net. It gives a great API that interfaces with Flickr and is accessible from C#.NET. You can find their page at http://www.codeplex.com/FlickrNet.

First thing is you will need to download the latest release, which at the time of writing this is 2.2.0.

After downloading it, extract the files and drop the FlickrNet.dll file into your bin folder.

After that its simply a matter of creating a page that utilizes this code.

Here is mine:

	Photos

	


        

	

		

			

				

					

						 
					

						<%#Eval("DateTaken") %> 
					

						">" style="float: left; padding-right: 15px;"> <%# GetDescription(Eval("PhotoId").ToString()) %>
						

							 
					
				
			
		
	







	

This is a simple repeater that uses some of the items that can be retrieved from Flickr.

My backend code looks something like this:

 int count = 10;

    int page = 1;

 

    protected void Page_Load(object sender, EventArgs e)

    {  

        if (Request.QueryString["page"] != null)

        {

            try

            {

                page = Convert.ToInt32(Request.QueryString["page"]);

            }

            catch

            {

                page = 1;

            }

        }

 

        PhotoRepeater.DataSource = RecentPhotos(page, count);

        PhotoRepeater.DataBind();

 

        Literal1.Text = GetNav(page, count);

        Literal2.Text = Literal1.Text;

    }

 

    public static string GetNav(int page, int count)

    {

        //String to return

        string returnstring = "";

 

        //If on the first page

        if (page == 1)

        {

            //Only show NEXT

            returnstring += "Next " + count + " >>";

        }

        //If not on the first page

        else

        {

            //Show PREVIOUS and NEXT

            returnstring += "<< Previous " + count.ToString() + "";

 

            //If the last page dont show NEXT

            if (page < GetNumPages(count))

            {

                returnstring += " | Next " + count.ToString() + " >>";

            }

        }

 

        //return the string

        return returnstring;

    }

 

    public static FlickrNet.PhotoCollection RecentPhotos(int page, int count)

    {

        FlickrNet.Flickr flickr = new FlickrNet.Flickr();

        FlickrNet.PhotoSearchOptions options = new FlickrNet.PhotoSearchOptions();

        options.UserId = ConfigurationManager.AppSettings.Get("UserId");

        options.PerPage = count;

        options.Page = page;

        options.SortOrder = FlickrNet.PhotoSearchSortOrder.DatePostedDesc;

        options.Extras = PhotoSearchExtras.All;

        FlickrNet.Photos photos = flickr.PhotosSearch(options);

        if (photos.PhotoCollection == null)

            return new FlickrNet.Photo[0];

        else

            return photos.PhotoCollection;

    }

 

    public static string GetDescription(string id)

    {

        Flickr flickr = new FlickrNet.Flickr();

        PhotoInfo p = flickr.PhotosGetInfo(id);

        return p.Description.ToString();

    }

 

    public static long GetNumPages(int count)

    {

        FlickrNet.Flickr flickr = new FlickrNet.Flickr();

        FlickrNet.PhotoSearchOptions options = new FlickrNet.PhotoSearchOptions();

        options.UserId = ConfigurationManager.AppSettings.Get("UserId");

        options.PerPage = count;

        options.SortOrder = FlickrNet.PhotoSearchSortOrder.DatePostedDesc;

        options.Extras = PhotoSearchExtras.All;

        FlickrNet.Photos photos = flickr.PhotosSearch(options);

       

        return photos.TotalPages;

    }  

Be sure to make sure you have "using FlickrNet;" at the top of the page.

I stored my Flickr UserId in my web.config in the appSettings section, but you can surely put it other places.

This code will yield something that looks like this:
